A Comprehensive, Simple, Robust, and Solvent-Free Method Covering Ultrashort- to Long-Chain PFAS in Atmospheric Samples.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ultrashort- and short-chain perfluoroalkyl and polyfluoroalkyl substances (PFAS), including trifluoroacetic acid (TFA), are emerging as widespread and persistent atmospheric pollutants of growing concern. Their atmospheric accumulation is further exacerbated by the transformation from various precursors, such as long-chain perfluorocarboxylic acids (PFCAs) and neutral PFAS. An efficient analytical method covering ultrashort- to long-chain PFAS is therefore required to monitor environmental levels and understand transformation mechanisms. However, distinct polarity among these PFAS poses technical challenges for simultaneous detection within a single run, hindering the comprehensive understanding of degradation mechanisms and quantitative correlation analysis. Conventional methods using liquid chromatography-electrospray ionization (LC-ESI) are effective for medium- to long-chain PFAS but are limited in detecting ultrashort-chain species concurrently. Herein, we present a simple yet robust method for broad-spectrum PFAS analysis, covering ultrashort- to long-chain species, using dielectric barrier discharge ionization (DBDI) coupled directly to high-resolution tandem mass spectrometry (HRMS/MS). This approach enables efficient ionization across a wide polarity range with reduced intensity of in-source fragmentation (ISF). Moreover, solid-phase microextraction (SPME) simplifies labor- and time-intensive sample preparation without solvents. As a result, a high sensitivity of 0.06-2.02 pg/m
